Is the entropy change of the ideal gas equals zero?

Click For Summary

Discussion Overview

The discussion revolves around the entropy change of an ideal gas, specifically questioning whether it is equal to zero and if it can be expressed as "Q/T" with given values for Q and T. The scope includes conceptual understanding and homework-related inquiries in thermodynamics.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant questions if the entropy change of an ideal gas is zero.
  • The same participant inquires whether the entropy change can be calculated using the formula "Q/T" with specific values for Q and T.
  • Another participant shares their personal experience of struggling with thermodynamics, indicating a lack of confidence in the subject matter.
  • A later reply indicates that the thread has been moved to a specific homework zone, suggesting a focus on educational support.

Areas of Agreement / Disagreement

The discussion does not present a consensus on the entropy change of the ideal gas, and multiple viewpoints regarding understanding and confidence in thermodynamics are evident.

Hi all!
I'm a bit puzzled about this question.
Is the entropy change of the ideal gas equals zero?
And for the second part, is it equal to "Q/T" where Q=200kJ and T=40+273?
I'm not sure about how to handle it...please help.

Please kindly help
 
Sorry mate, I failed thermo last semester. :D
Passing it this year though!

It does seem like this forum has too many novices for the experts to handle.
 
I've moved this thread to the college homework zone.
